Abstract: In view of the characteristics and construction difficulties of large-scale high-speed railway station buildings, using the private cloud computing platform to carry out BIM technology application, BIM+intelligent equipment application and BIM innovation application in the whole construction process, which will improve the project construction management level. Based on BIM and GIS, the whole life cycle management platform of steel structure is established to integrate various industries of intelligent construction site and form a BIM-based 3D intelligent construction site management system which lays a solid foundation for the smooth implementation of the project and contributes to the intelligent construction of railway station buildings.
